Family
Acrididae (short-horned grasshoppers) in the order Orthoptera (grasshoppers, katydids, crickets)
Description

The olive-green swamp grasshopper has a dark line through its eye, and the hind legs have bluish tibias (shin-like segments). Other key identifiers include the relatively long antennae, which are especially long in males. The antenna length is greater than the length of the hind femur (thigh-like segment).

This species is a member of the spur-throated grasshopper subfamily, in the short-horned grasshopper family. If you turn it upside-down, you will see a small pointy bump, or spur, where you would think its throat would be.
